FILLER FOB EGG-CASES.

Specification of Letters Patent.

Patented June 22, 1909.

Application filed December 23, 1907. Serial No. 407,670-

To all whom it may concern:

Be it known that l, Hnnmnrr B. Conmns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fillers for Ilgg-Uases, of which the following is a specification, reference being bad to the accompanying drawings.

My invention relates to packing cases for eggs and similar fragile articles, and particularly to a new and improved filler for such cases, and the object of the invention is to provide anew and improved filler which is designed more perfectly to protect the eggs and keep them from breaking, and particularly to provide a new and improved bearing strip for such tillers, which bearing other in the shipping cases with interposed flats of cardboard, or similar material, between the layers. The boxes are usually ciinstruct'ed with a central partition having a space upon each side of the central partition of suflicient size to contain a series of fillers, one above the other, each containing thirty-six or three dozen compartments The central partition being putin after the box is completed it frequently happens that it is not located exactly centrally, and hence, while the fillers it the box from side to side and the eggs are protected by the projecting ends of the cardboard strips from breakage, the compartments between the central partitionand the end of the box vary somewhat, so that the projecting ends are apt to become lbent over on the side where the compartnient is too short and do not quite reach the partition on the side in which the compartment isa little too long, causing the eggs to becon'ie brpken, particularly at the ends if: K

It is the i iljiject ief my invention to provide a filler \lIhichZ will obviate these abjections, and to jthis end it consists in providing the fillers with what may be called l- 4 l l i j bearing strips, located preferably at the ends of the tillers which come against the ends of the box and the central partition,

and which consist of a corrugated strip havlarger than the average size maybe placed.

In the dra\vings l igure l is an isometric view of a case containing my improved fillers with a portion of the case removed to show the construction more clearly; Fig. 2 is an enlarged detail, being a top or plan view of a portion of the corrugated bearing strip to show more clearly the form of corrugations.

.l'lelerring to the drawiugs -fi indicates a case divided by a central partition l. 5 indicates the fillers, which are composed of strips of cardboard 6'7 which are interlocked in the usual and well-known way, so that they may. be folded together flat for shipment. The strips 6-7 project at their ends, forming bearing projections 8 which are adapted to bear against the side of the box to keep the strips which lie adjacent thereto away from the sides of the box to Form an elastic bearing for the fillers against the box to 'n'event breakage.

9 indicates flats, which are placed between the ditl'erent layers of fillers.

l0 indicate bearing strips, which are lo cated preferably only at the ends of the fillers, as shown, so as to bear against the ends of the case and the intermediate partition 4. is best shown inFig. 2, the bearing strips are provided with cross or vertical corrugations consisting of deep corrugations 11 and shallower corrugations 12 intermediate the deep corrugations 11. The bearing strips 10 art secured to the filler by passing the ends of the strips 7 through the end pieces at the deeper corrugations 11' entering them from the convex side. As is best shown in Fig. 2, this arrangement is such that the shallower corrugations 12 are removed slightly from the end of the box or from the central partition 4-, bearing upon the box at the ends of'the deeper corrugations. The result of this arrangement-is that an allowanceis made for differences in length between the two partitionsof the box caused by the frequent slight misplacing of the central partition and the eggs in the end rows are protected from breakage when the box is shipped. The shallower intermediate corrugations also, it will be observed, form a some- What deeper row of cells at the end of the filler into which the slightly oversized eggs may be placed.

I have described my construction as hav ing my improved bearing strips only at the ends of the fillers Which bear against the ends of the box and the central partition, and this Will usually be suflicientas the boxes are usually accurately enough built as to Width to allow the projecting ends 8 to afford sufficient elasticity to prevent breakage in the outside rows of eggs toward the side of the box, but, of course,- my improved bearing strip maybe located upon all four sides of the filler, if desirable. I That which I claim as my'invention, and desire to secure by Letters Patent, is,. p v 1. A filler for cases comprised of a plurality of intersecting strips havingrorrugated bearing pieces secured at the outside ends of said strips, each of said corrugated beartions and intermediate shallower corrugations.

2. A filler for eggcases, consisting of a plurality of intersecting strips and corrugated bearing pieces having pairs oi deeper corrugations and intermediate shallower corrugations and secured to the ends of said intersect-ing strips at the convex portion of said deeper corrugations.

3. A corrugated bearing strip for egg fill- I ers having pairs of deeper transverse corrugations and intermediate shallower corrugations. l

i. A filler for egg cases, composed of a plurality of intersecting strips having corrugated bearing pieces secured at the out side end of said strips, each of said corru gated bearing pieces having between the secting strips-at the convex portion of said deeper corrugations. p v
